The receptor layer of the retina contains the cells — rods and cones — where the light triggers the nerve impulse which carries the visual information all along the visual pathways. The outer segments of receptor cells are structures specialized to convert light signals into electrical ones. These segments consist of regular stac kings of thousands of membranes loaded with the visual pigment — rhodopsin8. (Fig. 1).
